  Motor vehicle door and method of mounting.

  The present invention relates to a motor vehicle door and a method for mounting it on a vehicle body

with motor.

  Motor vehicle doors normally consist of

  by an outer coating and an internal frame

  the outer door covering from the press and comprising a steel sheet, a window frame and various sleepers, is mounted on the body of the motor vehicle on the assembly line, after which it passes, with

  the bodywork, through paint baths.

  A number of components are mounted, to a post off

  of the mounting cat, on the internal frame, coming from

  even the press and already equipped with a sheet metal coating

  metal and various sleepers; these components

  take, for example, the window, the lift mechanism

  glass, lock and panel or trim trim.

  Then, this internal frame is mounted permanently

  on the outer skin of the door arriving with the body of the paint bath, means being provided to match the lock mounted on the inner frame with a previously mounted latch on the door opening of the bodywork so as to be able to close that door and correct the possible mistakes in the form of the

  door siding, which could lead to

  misalignment of the edge of this coating with the

edge of the bodywork.

  However, during his transfer between the post o is

  the paint bath and through which pass the coach-

  door, and the station to which the internal framework, supplemented by the aforementioned components, is mounted on the coating, the latter, due to a possible misalignment of its edge with respect to the

  edge of the door opening of the bodywork for reasons

  sounds above, may strike protruding bodies, which may damage the paint that has just been applied. In addition, because it is impossible to ensure the closure

  the outer covering of the door in relation to the coach-

  the door is not yet equipped with its internal frame and, consequently, with its lock, it may happen that, after painting the bodywork and the door covering, the latter may move relative to

  to the bodywork so as to open wide towards the former

  interior, thus damaging the paint and possibly scaling, so it may be necessary to perform additional operations evident on this door, thus significantly increasing the production time

  and, as a result, the cost of the vehicle itself.

  The object of the present invention is to provide a door in which it is possible, with a particular mounting method, to guarantee the closure of the outer door covering and its correspondence with the bodywork at an earlier stage in comparison with the current technique. , so as to avoid the aforementioned drawbacks, this door being able to

  be easily manufactured and having a low cost of production.

  The present invention achieves these goals through a motor vehicle door having an outer door skin mounted on the mounting cat and an inner frame on which a plurality of components are mounted outside the assembly line, characterized in that a closing element cooperating with a striker mounted on the edge of the door opening of the bodywork of the motor vehicle is mounted on the outer door skin, while it is mounted on the internal frame an element

  aesthetic provided with a movable lamp.

  The invention will be better understood on reading the description of

  DETAILED DESCRIPTION FIG. 1 is an exploded view of the outer covering and the internal frame of a door, given by way of example only, of a preferred embodiment, in conjunction with the accompanying drawing. forming the subject of the present invention, the two parts being already equipped with a multiplicity of elements; and FIG. 2 is a perspective view of this framework

  internal view from the opposite side to that shown in Figure 1.

  As can be seen in Figure 1, an outer door skin is identified as a whole at 3; it is made by stamping so as to have at its lower part a crosspiece 4 across the coating 6 which terminates at the top by a frame 7 defining the opening

from the door window.

  A groove 8, intended for housing a band of water

  not shown in the figure, is formed around the

  the entire perimeter of this window frame.

  Meant closure or lock 10 is fixed on a portion of the inner face of the coating 6 and cooperates with a keeper 11, shown in phantom in Figure 1, previously mounted on the edge of the door opening of the vehicle body at

  motor in correspondence with this lock.

  An internal framework, identified as a whole at 14, is formed by stamping so as to have a portion of box 16, visible in the drawing, from which a series of

  sleepers 18 on which are fixed a support 20 des-

  intended to serve as a stop for locking a window holder 24, forming part of a window regulator unit 26, and two eyecups 28 provided for slidably receiving a cable

  flexible 30 also forming part of the window regulator unit.

  On a third cross member of the marked series 18, are respectively mounted a control wheel mechanism 32 forming part of the window regulator unit and a control mechanism 34 of the door lock, with an associated transmission 36, provided to be connected on one side to the lock 10 and on the other to a lever 38 incorporated in a mounting 40

visible in Figure 1.

  On both sides of the inner front wall of the portion

  of box 16 are fixed two slides 42 visi

  2 and each having a U-passage 44 for containing a non-visible sealing strip on the

  Figure 2; in these passages 44 are slidably housed

  the edges of a window 46 fixed otherwise by any known means, for example by elastic pins, on the

window holder 24.

  A covering panel 48 is provided in its upper part with an articulated flap 50, visible in FIG.

  obtained by a dielectric weld bead creating an

  Ligamentary ligament 52 which extends over the entire length

of the panel.

  This flap can pivot about the axis of this joint and take two limit positions, one in which it is perpendicular to the plane of the panel (Figure 1) and is thus open, while in the other position it is aligned by

  relative to the wall of the panel and is thus closed.

  On this panel of dressing are also formed two

  elements (not visible in the drawing) which are respectively provided, one for the attachment of the assembly 40 incorporating the lever 38 and the other for the attachment of a crank 53, intended to be connected to a shaft 54, visible on FIG. 2, forming part of the control mechanism 32 of the

window.

  An armrest 56 is provided to be mounted on the trim panel by fixing this armrest on one of the sleepers

  18 of the box 16 so as to close the panel between them.

  In addition, the trim panel may optionally be

  equipped with various fasteners and various housing for the in-

  troduction of loudspeakers for the vehicle radio and

  pockets or cavities for documents, not representative of

on the drawing.

  The assembly process will now be described.

  From the stamping station, the outer coating 3, already preformed as a whole with the sheet 6, the crosspiece 4 and the frame 7, arrives on the assembly line where the bodywork, on which the latch has already been mounted, is

in transit.

  Similarly, but at a station outside the assembly line, where are the elements mentioned above, arrives the internal frame 14 already preformed as a whole with

  the box portion 16 and the cross members 18.

  The outer cover of door 3 is mounted on the coach-

  the vehicle by attaching the joints of which it is

  provided on the body with nuts and screws.

  After that, the body with the door siding follows the assembly line passing through the paint baths to then arrive at the post at which

  the lock 10 is mounted on a section of the inner face

  re of the sheet 6 in correspondence with the striker 11, and a

  sealing strip is housed in the groove 8 of the frame

7.

  At this station is also provided the adjustment of the lock 10 relative to the striker 11 disposed on the edge of the opening of the door in the bodywork so as to ensure the closure of the outer door skin with respect to the bodywork and correct, in this closed position,

  any possible misalignment of the edge of the outer coating

  door at the edge of the bodywork of the motor vehicle due to errors in shape, At this stage, the outer door covering, fully closed on the bodywork, moves along the assembly line towards the control station. next assembly, that is to say the one to which the internal frame of the door already equipped with

  previously described elements must be mounted.

  In the meantime, in the station outside the assembly line, the support 20 and the two eyelets 28 are mounted on the crossmember 18 of the box 16 of the inner door frame; After that, the display unit 26, already equipped with the flexible cable 30, the mechanisms of the control wheel 32 and the glass holder 24, is mounted by introducing the flexible cable 30 through the two eyecups 28 and placing

  and fixing the glass holder 24 on the support 20.

  Then, the two guide rails 42 are fixed on the box portion 16 by arranging them at a distance from one another, after introduction of two strips.

  in their passages 44, the sliding housing

edges of the glass 46.

  After that, the window is mounted on the window-holder 24 by known means, for example elastic pins, thereby securing the window pane of

the window regulator unit.

  After that, the actuating mechanism of the door lock 34 and the associated transmission 36 are mounted on

one of the sleepers 18.

  Then, the covering panel 48, already preformed with the various housings and the hinged flap formed by the continuous dielectric weld bead is fixed against the edges of the outer face of the box portion 16, housing the crank 53 in a first opening in the cladding panel and connecting it to the shaft 54 of the control wheel mechanism 32 so as to enable the vertical movement of the window 46 to be controlled and by positioning the assembly 40 incorporating the lever 38 in a second opening putting this lever in connection

  with the actuating mechanism of the door lock 34.

  The armrest is then fixed on the covering panel by fixing it on one of the cross-members 18 so as to grip

the panel between them.

  At this stage, the internal frame equipped with the elements described above is brought to the assembly station where the bodywork with the outer door covering already equipped with the

  lock arrives from the paint bath with the complete door-

  In this position, the inner frame is mounted on the outer skin by applying the inner face of the casing 16 against the inner face of the covering 6 and fixing them to

  the other by means of screws and nuts.

  - After that, the operating device of the door lock 34 of the internal frame is connected to the lock of the outer covering by means of the transmission 36 by bringing the latter manually to the lock 10 by the passage left free by the open position taken by

  the hinged flap 50 by rotating it.

  After these operations, the articulated flap 50 is brought in the opposite direction to that described above until it comes to apply with its inner face against the faces of the box portion 16, and the flap

  articulated is then fixed on the portion of caisson A this sta-

  from, the door is finished and can move forward with the coach-

  from the vehicle to the next assembly station.

  As it appears from the description above, the conformity

  particularity of the cladding panel allows a process

  of assembly thanks to which one obtains a door on the

  outside of which a cooperative lock can be

  with a strike mounted on the edge of the opening of

  door of the bodywork of the motor vehicle as soon as

  In this way, the lock can be adjusted with respect to the striker, and any errors in shape which cause the displacement of the edge of the door can be corrected.

  door siding with respect to the edge of the door

  door opening, which misalignment could cause when moving out of paint baths, scratches on the latter caused by

salient bodies.

  Moreover, since the outer coating can be locked

  door on the body by the cooperation of the lock on the coating with the striker on the body, it prevents any movement of the outer coating relative to the body and therefore avoids the

  possible damage caused by various objects.
